WHERE T.RNUM  BETWEEN ( 0 /**P*/+1) AND ( 0 /**P*/+ 10 /**P*/)

Что я уже пробовал:

Я изменился как на

AND ROWNUM BETWEEN ( 10 /**P*/+1) AND ( 10 /**P*/+ 10 /**P*/)
ORDER BY B.REG_DTM DESC

но не работает, когда вторая страница

AND ROWNUM BETWEEN ( 10 /**P*/+1) AND ( 10 /**P*/+ 10 /**P*/)
ORDER BY B.REG_DTM DESC
